Foods with Vitamin B1

Vitamin B1 is often labeled as thiamin. This vitamin is responsible for helping to create energy from dietary carbohydrates and fats. It also supports the nervous system. Vitamin B1 was first isolated in 1926 as part of a search for treatments for beriberi. People may have low levels of B1 if they are suffering from beriberi, nerve inflammation or pellagra. Pregnancy can also cause naturally low levels of vitamin B1.

An excess of vitamin B1 in the body is typically caused by diet. Adults over 19 years of age require between 1.1 milligrams and 1.2 milligrams per day. Pregnant and breastfeeding women require 1.4 milligrams per day. Infants up to six months of age require 0.2 milligrams daily. Children between the ages of six months and 12 months old require 0.3 milligrams daily. Children between the ages of one and three years of age require 0.6 milligrams daily. Children between the ages of four and eight years of age require 0.9 milligrams daily. Teen between 14 and 18 years of age require up to 1.2 milligrams daily.
